Definitions
- the present invention relates generally to irrigation machines and, more particularly, to a system, method and apparatus for spraying the leaf and root areas of plants.
- Modern field irrigation machines are combinations of drive systems and sprinkler systems. Generally, these systems are divided into two types depending on the type of travel they are designed to execute: center pivot and/or linear.
- common irrigation machines Regardless of being center pivot or linear, common irrigation machines most often include an overhead sprinkler irrigation system consisting of several segments of pipe (usually galvanized steel or aluminum) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length. These machines move in a circular pattern (if center pivot) or linear and are fed with water from an outside source (i.e. a well or water line).
- the essential function of an irrigation machine is to apply an applicant (i.e. water or other solution) to a given location.
- mechanized irrigation machines are primarily designed for transport and for efficiently delivering water to a soil surface for uptake by root systems.
- growers are able to apply certain chemicals through the irrigation water that are beneficial.
- the chemicals are applied broadly across the cultivation area in the same manner as the irrigation water. In many cases, this type of broad application is wasteful as chemical applications must generally be more focused or applied in a different way for effective treatment.
- irrigation sprinklers are not designed to apply the fine mist and low flowrates required for leaf adherence of chemicals applied by foliar application.
- the present invention provides a system, method and apparatus for spraying the leaf and root areas of plants with specialized equipment mounted on, but fluidly separate from the irrigation machine.
- the present invention provides a foliar chemical application package which is designed specifically to deliver a chemical solution to the leaf area of plants in which the chemical will primarily enter the plant through the foliar area and/or root ball rather than generalized absorption from the irrigated soil.
- the present invention teaches a system, method and apparatus for providing a specialized foliage spraying application in which water supply lines and chemical supply lines are individually controlled so that applicants, such as water, or different chemicals received from different chemical tanks, may be simultaneously or separately applied to a given crop.
- brackets may attach chemical transmission lines to water pipelines.
- the system preferably may be configured to allow for a complete flush/evacuation of dedicated chemical lines to purge each pipe of chemicals following an application.
- the dedicated chemical transmission lines and distribution sprayers/emitter/drops may preferably be formed of materials which are resistant to chemical and UV exposure.

Abstract
Description
- The present application claims priority to U.S. Provisional Application No. 62/649,435 filed Mar. 28, 2018 and to U.S. Provisional Application No. 62/649,619 filed Mar. 29, 2018.
- The present invention relates generally to irrigation machines and, more particularly, to a system, method and apparatus for spraying the leaf and root areas of plants.
- Modern field irrigation machines are combinations of drive systems and sprinkler systems. Generally, these systems are divided into two types depending on the type of travel they are designed to execute: center pivot and/or linear.
- Regardless of being center pivot or linear, common irrigation machines most often include an overhead sprinkler irrigation system consisting of several segments of pipe (usually galvanized steel or aluminum) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length. These machines move in a circular pattern (if center pivot) or linear and are fed with water from an outside source (i.e. a well or water line). The essential function of an irrigation machine is to apply an applicant (i.e. water or other solution) to a given location.
- In most cases, a mechanized irrigation machine's primary purpose has been applying water for irrigation. Accordingly, mechanized irrigation machines are primarily designed for transport and for efficiently delivering water to a soil surface for uptake by root systems. In some cases, growers are able to apply certain chemicals through the irrigation water that are beneficial. However, there are many limitations to the effectiveness and efficiency of applying a variety of chemicals by traditional means. For example, by utilizing the existing irrigation plumbing, chemical application cannot be applied at higher concentrations and must be diluted in order to increase the application volume to be compatible with the irrigation sprinklers. Secondly, the chemicals are applied broadly across the cultivation area in the same manner as the irrigation water. In many cases, this type of broad application is wasteful as chemical applications must generally be more focused or applied in a different way for effective treatment. Finally, irrigation sprinklers are not designed to apply the fine mist and low flowrates required for leaf adherence of chemicals applied by foliar application.
- In order to overcome the limitations of the prior art, a system is needed which is able to effectively apply chemicals utilizing irrigation machines without compromising the ability of the irrigation machines to apply irrigation water effectively and efficiently.
- To minimize the limitations found in the prior art, and to minimize other limitations that will be apparent upon the reading of the specifications, the present invention provides a system, method and apparatus for spraying the leaf and root areas of plants with specialized equipment mounted on, but fluidly separate from the irrigation machine.
- According to an exemplary preferred embodiment, the present invention provides a foliar chemical application package which is designed specifically to deliver a chemical solution to the leaf area of plants in which the chemical will primarily enter the plant through the foliar area and/or root ball rather than generalized absorption from the irrigated soil.
- According to a further preferred embodiment, the present invention teaches a system, method and apparatus for providing a specialized foliage spraying application in which water supply lines and chemical supply lines are individually controlled so that applicants, such as water, or different chemicals received from different chemical tanks, may be simultaneously or separately applied to a given crop.
- According to further preferred embodiments, brackets may attach chemical transmission lines to water pipelines. Still further, the system preferably may be configured to allow for a complete flush/evacuation of dedicated chemical lines to purge each pipe of chemicals following an application. According to further preferred embodiments, the dedicated chemical transmission lines and distribution sprayers/emitter/drops may preferably be formed of materials which are resistant to chemical and UV exposure.
